How it works

1. Save your bike. Look it up by make, model and year. Claude fills in the key specs — wheel size, groupset, axle standards, brake type. You can correct anything it gets wrong.

2. Search for compatible parts. Use Compatible parts to pick a category (cassette, wheelset, brakes…) and get eBay listings that are confirmed compatible with your exact bike — no guessing whether something fits.

3. Each result is scored. A compatibility score shows how well a listing matches your bike's specs. Hard requirements (freehub, axle standard) are checked separately from soft preferences.

All results are eBay listings. Clicking a title opens the listing directly on eBay.
